Wilfrid Laurier University offers both a BA and a BSc in Computer Science. I'm considering taking one of the programs. What I'm wondering is... How useful would a BA in Computer Science be? Wouldn't most employers want a BSc?

It is .If you want to make a living as a software developer I'd suggest the BSc, from experience the BA definately is less technical (read also less programming) [That's all based on the assumption that these things work in the US as the do in the EU though...]

EDIT: A BA may be interessting additionally to a BSc, but that depends on the type of BA and on your ideas for a future job...

Yup, and being forced to go through it isn't fun but I suppose in programming you need some working knowledge of core concepts they teach (how to write proofs, proving using induction, automata, algorithms, etc.). Can't picture myself diving my head into computational theory.

Speaking of math, some of those guys take our CS courses as their GPAs are high enough to let them in without being in a CS program. And one of those guys that came in was kinda snarky... *shakes fist*

On topic, as previously mentioned focus more on what courses you're taking, than the name of your concentration/specialist/major/etc.
